One word I refuse to mispronounce by emphasizing the letter L is solder. There is a youtuber gaining in popularity that sells a sticker of a fish wearing a top hat and jacket while holding a soldering iron and it says "Colonel Lincoln the Soldering Salmon".Sorry, the word solder has to have the L pronounced, otherwise you're saying 'sodder' which always sounds to me like 'sod her' and makes me think what poor woman are they having a rant about..?
Here in the UK it's pronounced 'Soul-der' abnd woe betide any bloke who says 'sod her' to my face
